JOHANSEN, OF MICHIGAN CITY, INDIANA, ASSIGNOR TO SULLIVAN MA- CHINERY COMPANY, A CORPORATION OF MASSACHUSETTS DRILLING APPARATUS Application'filed February 26, 1927. Serial No.'171,345.

This invention relates to drilling apparatus and more particularly to an improved portable oil and gas well drilling apparatus of the rotary core type.

- The object of this invention is to provide an improved portable oil and gas well drilling apparatus. Another object of this invention is to provide a rotary core drilling apparatus mounted on a wheeled truck frame and having improved means for shifting the drill relative to the truck frame. Still another object of this invention is to provide an improved hydraulic transfer device for shifting the drill relative to the truck frame and more especially to move the drill toward or away from the drill hole during hoisting and lowering of the rod line in the hole. These and other objects of the invention will, however,hereinafter more fully appear.

In the accompanyin drawings there is shown for purposes of illustration one form which the invention may assume in practice.

In these drawin s,

Fig. 1 is a side e evational view of the improved drilling apparatus, parts being shown in section to illustrate details of construction.

Fig. 2 is a central longitudinally extending horizontal sectional view taken substantially. on line 22 of Fig. 1 and illustrating the improved hydraulic transfer cylinder.

Fig. 3 is a transverse vertical sectional view taken on line 33 of Fig. 1.

Fig. 4 is a transverse vertical sectional %iew, taken substantially on line 4-4 of In an illustrative embodiment of the invention there is shown a truck frame 1 mounted on wheels 2 and presenting parallel longitudinally extending guideways 3.

Mounted on the truck frame 1 for longitudinal movement relative thereto is a frame 4 on which the various elements of the drilling apparatus are supported as will later be described. The frame 4 is provided with parallel guideways 5 which cooperate with the guideways 3 on the truck frame 1. As.

illustrated, supported byv the sliding frame .4 at the forward end thereof is a gasoline engine 6 of standard construction, the frame 4 having. an opening 7 through which the lower portion of the engine 6 depends. Also formed on the frame 4 at the forward end thereof is a transverse portion 8 on which the forward end of the driving engine 6'is supported. The transmission shaft 9 of the engine 6 is operatively connected through a usual plural speed transmission mechanism 10 to the driving shaft 11 of the usual rotation mechanism 12 for the drill rod 13. The drill rod 13 is connectible to ausual tool carrying rod line in a well known manner. As is usual in drilling apparatus of the type disclosed, the drill rod 13 is adapted to be fed upwardly or downwardly by means of a hydraulic feeding mechanism 14 which herein may be of the type disclosed in my copending application, Serial No. 157,249, filed Dec.

27 1926. A usual swivel head 15 is also pro vided for rotatably supporting the drill rod 13 and the usual tool carrying rod line. As clearly shown in Fig. 1 the drill driving shaft 11 is adapted to drive through gearin 16 a usual hoisting drum 17 the drum 1? being suitablyrotatably mounted on the sliding frame 4. As the specific construction of the drill rod rotating mechanism, the feeding mechanism, and the hoisting mechanism does not enter into this invention further detailed description of the same is considered unnecessary. Referring to Figs. 1 and 4 it will be noted that also mounted on the frame 4 by means of a suitable bracket 18 is a hydraulic pump generally designated 19 and this pump is adapted to be driven from the engine transmission shaft 9 by means of an endless drive chain 20 under the control of a suitable clutch mechanism 21. The pump 19 is adapted to supply water under pressure to the I hydraulic feeding mechanism 14 through a hose connection 20 and through a branch hose connection 21 and thence through the rod line to the bottom of the drill hole. From the foregoing description it will be evident that the sliding frame 4 is slidable, together with the elements of the drilling apparatus su ported thereon, bodily relative to the truck rame 1.

The improved hydraulic transfer device as shown in the drawings specifically comthe sides of the latter by brackets 23 and 24 secured to transverse plates 25. The plates 25 are suitably rigidly secured to the side members of the truck frame 1. As shown in Fig. 2 the cylinder 22 comprises a tubular member 26 and cylinder heads 27 and 28 herein preferably formed integral with the brackets 23 and 24 respectively. The cylinder member 26 and the head members 27 and 28 are held in rigid assembled relation by means of tie rods 29. The cylinder 22 contains a piston 30 having a piston rod 31 extending rearwardly through a suitable stufling box 32 carried by the rear cylinder head 27. 7 As shown the piston rod 31 extends rearwardly of the truck frame and is rigidly secured at 33 to the sliding frame 4. The opposite ends of the cylinder 22 are connected by pipe connections 34 and 35 to a usual four way valve 36. The valve 36 is alsoconnected, through flexible pipe connections or hoses 37 and 38, to the pump 19, the connections 37 and 38 being connected to the pump 19 at 39 and 40 respectively. The four way valve 36 is provided with an operating rod 41 extending laterally through the side of the truck frame 1 and has secured thereto a handle 42.

In the operation of the improved drilling apparatus when it is desired to shift the drilling apparatus relative to the drill hole to permit raising or lowering of the rod line in the hole the hydraulic is disconnected from the rod line and the operator then manipulates the valve 36 thereby connecting the pipe connection 34 leading to the rear end of the transfer cylinder 22 with thesupply connec tion 37 leadin from the pump 19. Simultaneously the ront end of the cylinder 22 is connected through the pipe connection 35 with the pipe connection 38 through which the return fluid is conducted to the intake of the pump 19. Consequently the pump 19 which is driven by the engine 6 forces water under high pressure through the pipe connections 37 and 34 to the rear end of the cylinder 22 and the piston 30 is forced forward-1y in the relatively stationary cylinder. As the 1 piston rod 31 is connected to the sliding frame 4 the latter, together with the elements of the drilling apparatus supported thereon, are moved relative to the truck frame 1 and away from the drill hole to the position indicated by dotted lines in Fig. 1. It will be evident that by suitably controlling the valve 36 hydraulic pressure may be admitted within the front end of the cylinder 22 while the rear end of this cylinder is connected to the return pipe 38. Resultantly the piston 30 will move rearwardly within the cylinder 22 and the frame and elements of the drilling appa-- ratus supported thereon will then be moved to their initial position.

As a result of this invention it will be noted that an improved hydraulic transfer device for a portable oil or gas well drilling apparatus is provided, whereby the drill may be shifted with facility relative to the truck frame. It will be further evident that by mounting the gasoline driving engine together with the elements of the drill on asingle sliding frame and by shifting the sliding frame bodily relative to the truck frame it is possible to greatly simplify the driving connections between the engine and the drill, no telescopic or sliding connections being necessary. Furthermore it will be noted that an improved drill shifting mechanism is provided, which is of an exceedingly rugged and its spirit or the scope of the appended claims.
